DNA History
The Canadian biologist who refined Griffith's transformation experiments with heat-killed and live bacteria and mice to find that transformation ONLY occurred when DNA was present.
Who is Oswald Avery?
The name for the shape of DNA structure.
What is a double helix?
The group of biomolecules to which DNA belongs.
What is nucleic acids?
The situation that requires DNA replication.
What is cell division?
What the original mRNA strand is complementary to.
What is the DNA template (the gene)?
The two American scientists who did the elegant experiment involving the radioactive labeling of bacteriophage protein coat and contents to prove DNA was the genetic material.
Who are Alfred Hershey and Martha Chase?
Nitrogen bases are always attached to this on the DNA backbone.
What is deoxyribose?
The information to make a protein is located here in DNA.
What is the sequence of bases?
ALWAYS the direction of DNA assembly.
What is 5' to 3'?
The non-coding parts removed from the original mRNA and the location where it happens.
What are introns and nucleus?
The American biochemist whose work established the base pairing rule.
Who is Erwin Chargaff?
The base that always pairs with adenine in DNA.
What is thymine?
The molecule made during transcription.
What is messenger RNA?
The strand assembled TOWARD the replication fork.
What is the leading strand?
The coding parts spliced together to make the final mRNA, and the location where it happens.
What are exons and nucleus?
The four discoverers of DNA structure.
Who are Franklin, Wilkins, Crick and Watson?
The base that always pairs with cytosine.
What is guanine?
The three world definition for replication.
What is DNA making DNA?
The strand that requires Okazaki fragments for its assembly.
What is the lagging strand?
The location and organelle where translation occurs.
What are cytoplasm and ribosome?
Reason Rosalind Franklin did not receive a Nobel Prize for her amazing x-ray crystallography that helped solve the structure of DNA.
What is her early death, likely caused by radiation exposure during her landmark research?
The name for the opposite 3' to 5' alignment of the two sides of a DNA strand.
What is anti-parallel?
The other two organelles, in addition to the nucleus, that contain their own DNA.
What are mitochondria and chloroplasts?
Enzymes of replication, in order.
What are helicase, topoisomerase, primase, DNA polymerase and ligase?
The item that assists in assembling the final mRNA so it can leave the nucleus for translation.
What is the spliceosome?
